RAYON SPINNING MACHINE Filed Jan. 17, 1931 lNVENTOR ATTORNEY Patented Jan. 3, 1933 CONRAD HERRMANN, F VfUPPER'IAL-ELBERFELD, GERMANY, ASSIGNOR T0 AMEBIGAN GLANZSTOFF CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF DELAW'ABE RAYON SPINNING MACHINE Application filed January 17, 1931, Serial No. 509,511, and in Germany January 20, 1930.

The rayon spinning machines now in use have a disadvantage in that the thread remains in the setting bath during the exchange of the take-up spool after finishing the spinning process. This forces the thread to form a ball which may interfere with the process of spinning. Furthermore, this thread ball cannot be used in any way so that there is considerable waste of yarn. Attempts have been made to install a second spool which could wind up the thread during the exchange of the take-up spool, the yarn of which can be used as staple fibre. This arrangement, however, has a disadvantage in that it makes the construction of the machine much more complicated and consequently also increases its cost.

The object of my present invention is to provide a new type of rayon spinning machine which will eliminate all the above mentioned disadvantages. The invention consists essentially of an arrangement by which the machine is provided with a traveling spool for taking up the thread during the exchange of the take-up spool which can be brought to the spinning place where an exchange of the take-up spool is required.

This has the following advantage: the

thread which is spun during the exchange can be wound up, and furthermore, this will not necessitate having an extra spool for each spinning place. This will greatly simplify the construction of the machine. The exchange spool is fastened to a car the wheels of which run on rails attached to the machine so that the exchange spool can be moved along the machine. This moving is best done by hand on centrifugal spinning machines and automatically on spool spinning machines by means of an endless chain or a similar arrangement.

The spool may be driven directly by a motor or by a belt transmission. An auto matic arrangement is more suitable for the spool spinning machines so that the full spools can be exchanged one after the other.

The drawing shows an example of how the object of this invention can be arranged:

Figure 1 is a plan view of part of a centrifugal machine; and

Figure 2 is a cross sectional view of Figure 1. The thread 6 comes from the spinnerette a, passing over the take-up spools 0 to centrifuge (Z. The rails f, f are arranged on the frame 6, on which the wheels 9, g of the carriage h operate. The exchange spool may also be driven by belt transmission on spool spinning machines which will at the same time move the carriage h, which is shown in the example as being driven by belt transmission on spool spinning machines which will at the same time move the carriage h backwards and forwards automatically by means of an endless chain. With this arrangement it is possible to wind the thread on the exchange spool where an exchange of the spool becomes necessary and the yarn can then be used as staple fibre.

*Iaving now fully disclosed my invention as required by the patent statutes, what I claim is:

1. ran artificial silk spinning machine provided with an exchange spool adapted to wind or take up the yarn produced during the changing of the take-up means, and means carrying said exchange spool and mounted for traveling from one take-up means to the next.

2. An artificial silk spinning machine provided with a traveling exchange spool adapted to wind or take up the yarn produced during the changing of the take-up means, the said traveling spool being attached to a carriage the wheels of which run on rails fastened to the machine.

3. An artificial silk spinning machine provided with a traveling exchange spool adapted to wind or take up the yarn produced during the changing of the take-up means, the said traveling spool being attached to a carriage the wheels of which run on rails fastened to the machine and being driven directly by a motor.

L. In a machine for spinning artificial filaments, a plurality of spinning devices each including take-up means for the filaments, an exchange spool adapted to take up the filaments during the changing of the take-up means, and means carrying said exchange spool and mounted for traveling from one take-up means to the next.

5. In a machine for spinning artificial filaments, a plurality of spinning devices each including take-up means, an exchange spool adapted to take up the filaments during changing of the take-up means, a traveling carriage adapted to move from one take-up means to the next and having an arm extend V mount ing from the carriage, and means to the exchang'e'spool on the arm.

6. In a. machine for spinning artificial silk,- v a plurality of spinning devices each including take-up means, an exchange spool adapted to take up the filaments during changing of the take-up means, a traveling carriage ada'ptedto run on arail and having an arm extending from the carriage, means to mount the exchange spool on the arm, and means carried by, the'arm for driving the spool.

7. In a spinning machine With a plurality of take-up means, a traveling exchange spool adapted to he moved from one take-up means to another for the reception of the thread While changing the take-up means.

'8. In a spinning machine With a plurality of take-up means, an exchange spool mounted on a carrieradapted to he moved from one take-up means to another for the reception of the thread While exchanging the take-up means, and means mounted on the carrier for driving the exchange spool.

9. In a spooling machine having a plurality of take-up spools for thread, a traveling exchange spool associated therewith and movable to selective position, adjacent any of the said take-up spools during the doffing thereof.

In testimony whereof I aflix my signature.
